Abstract
Description
Technisches GebietTechnical field
Die Erfindung bezieht sich auf eine Vorrichtung zum Empfang digitaler Signale zwischen mehreren gegeneinander beweglichen Einheiten.The invention relates to a Device for receiving digital signals between several against each other moving units.
Der Übersichtlichkeit halber wird in diesem Dokument nicht zwischen der Übertragung zwischen gegeneinander beweglichen Einheiten und einer feststehenden und dazu beweglichen Einheiten unterschieden, da dies nur eine Frage des Ortsbezugs ist und keinen Einfluss auf die Funktionsweise der Erfindung hat. Ebenso wird nicht weiter zwischen der Übertragung von Signalen und Energie unterschieden, da die Wirkungsmechanismen hier die selben sind.For the sake of clarity in this document not between the transfer between each other movable units and a fixed and movable Units, as this is just a question of location and has no influence on the functioning of the invention. As well will not continue between the transfer distinguished from signals and energy because the mechanisms of action are the same here.
Stand der TechnikState of the art
Bei linear beweglichen Einheiten wie Kran- und Förder- anlagen und auch bei drehbaren Einheiten wie Radaranlagen oder auch Computertomographen ist es notwendig, zwischen gegeneinander beweglichen Einheiten elektrische Signale bzw. Energie zu übertragen. Hierzu ist meist eine Leiterstruktur in der ersten Einheit und ein entsprechender Abgriff in der zweiten Einheit vorgesehen. In den folgenden Ausführungen bezieht sich der Begriff Leiterstrukturen auf alle denkbaren Formen von Leiterstrukturen, welche geeignet sind, elektrische Signale zu führen. Dies bezieht sich auch auf die bekannten kontaktierenden Schleifbahnen bzw. Schleifringe.For linearly moving units like crane and conveyor systems and also with rotating units such as radar systems or computer tomographs it is necessary to electrical between mutually movable units To transmit signals or energy. There is usually a ladder structure in the first unit and a appropriate tap is provided in the second unit. In the following versions The term ladder structures refers to all conceivable forms of conductor structures which are suitable for electrical signals respectively. This also refers to the known contacting slideways or slip rings.
